first thing to do as far as im concerned is to get rid of that card number, that way amazon can't charge it straight away, that one and every single fuckin one that you ever used on amazon just to be sure;
by the time it gets to paper invoices you might have some better channels of communication to make a point about how it obviously wasn't you, cause at the moment it doesn't sound like you're dealing with any capable process

If I block my card and ask my bank for another one, will that really prevent Amazon from debiting me again? Because they have the account information that is linked to that card, right?

How would they do that without valid card on file?
